A nurse is collecting data from a client who received diphenhydramine 1 hr ago after developing an allergic reaction to trimethoprim-sulfamethoxazole.
Which of the following statements by the client should indicate to the nurse that the medication is effective?

Choice A rationale:

The first dose of the varicella vaccine is usually given when the child is between 12 to 15 months old, not after 3 years.

Choice B rationale:

Aspirin should not be given to children due to the risk of Reye’s syndrome. This syndrome is a rare but serious condition that causes swelling in the liver and brain.

Choice C rationale:

The varicella vaccine should be avoided in children who have leukemia or any other condition that weakens the immune system.

Choice D rationale:

The varicella vaccine is not contraindicated for children who are allergic to eggs. It’s some other vaccines like influenza that have this restriction.

Choice A rationale:

Hoarseness of voice can be a symptom of an allergic reaction, indicating swelling and inflammation in the throat. If the client’s voice is no longer hoarse after taking diphenhydramine, it suggests that the medication has been effective in reducing this symptom.

Choice B rationale:

Diphenhydramine is an antihistamine and can often cause drowsiness as a side effect. Therefore, feeling more alert would not typically indicate that the medication has been effective.

Choice C rationale:

While headaches can sometimes be associated with allergic reactions, they are not a primary symptom that diphenhydramine targets. Therefore, absence of a headache does not necessarily indicate effectiveness of the medication.

Choice D rationale:

Increased appetite is not typically associated with the effectiveness of diphenhydramine in treating allergic reactions.
